Title: Pipe cleaning tool and method of using
Inventor: ERICH RICHARD R
IPC: B08B9/045
Filed: 1995-09-01
Abstract: A pipe cleaning tool (10) employing a cutting head (12) and propulsor (14) utilizes a plurality of roller cutters (18) on the cutting head (12). The rolling cutters (18) are coupled in a pairwise fashion to a rotatable car (72). The rotatable car (72) in turn is pivoted to the cutting head (12). Each of the cars (72) and, hence, the radial disposition of each of the roller cutters (18), is resiliently urged into a preferred radial disposition relative to the longitudinal axis of the cutting head (12). The pairs of roller cutters (18) are combined with a hydrolasing action with a following cutter disk (16) having a plurality of nozzle cuts (88) defined through its radial periphery. A rotatable tracker (96) is combined with the tool (10) to provide an electromagnetic signal directly indicating flow of fluid past the tool (10).

Title: Optical network termination unit of a hybrid fiber/coax access network
Inventor: KRIMMEL HEINZ
IPC: H04B10/25
Filed: 1997-10-15
Abstract: In a hybrid fiber/coax access network (NET) with a forward channel and a return channel, the return channel serves to transmit voice and video signals as well as data signals from groups of terminals (NT1; NT2) to a subcenter (HUB). Access by a group of terminals (NT1; NT2) to a shared electric line (KOAX1; KOAX2) is obtained by TDMA, FDMA, or CDMA, for example. An optical network termination unit (ONU) is connected to one or more electric lines (KOAX1; KOAX2). For each line or for each separate frequency range of the return channel, the optical network termination unit (ONU) contains an analog-to-digital converter (A/D1, A/D2) which digitizes the received signal. If two or more analog-to-digital converters (A/D1, A/D2) are provided, the individual digitized signals are multiplexed in a multiplexer (MUX) and then fed to a digital electrical-to-optical transducer (E/O2). The electrical-to-optical transducer (E/O2) converts the multiplexed signals to optical signals, which are then transmitted over an optical cable (FIBRE) to the subcenter (HUB), where they are processed digitally.
Patent CA-2218244-A1 (CA)
Title: Reduced complexity signal transmission system
Inventor: DE BONT FRANSISCUS MARINUS JOZ
IPC: G10L19/12
Filed: 1997-01-31
Abstract: In a CELP coder a comparison between a target signal and a plurality of synthetic signals is made.      The synthetic signal is derived by filtering a plurality of excitation sequences by a synthesis filter having parameters derived from the target signal. The excitation signal which results in a minimum error between the target signal and the synthetic signal is selected. The search for the best excitation signal requires a substantial computational complexity. To reduce the complexity a preselection of a small number of excitation sequences is made using a reduced complexity synthesis filter. With this small number of excitation sequences a full complexity search is made. Due to the reduced number of excitation sequences involved in the final selection the required computational complexity is reduced.

Patent CA-2231860-A1 (CA)
Inventor: LAHTINEN TERHO
IPC: B29C48/94
Filed: 1996-09-20
Abstract: The invention relates to an extruder with which material is extruded through a tool (2). Fluoropolymer is used between the extrusion material and the tool (2) for reducing friction between the material and the tool. At least the surface of the tool (2) against fluoropolymer is if a material whose thermal conductivity is greater than the thermal conductivity of ordinary tool steel. Therefore the friction heat generated can be conducted efficiently away from the interface between the tool (2) and the extrusion material towards the tool (2), whereby the wear of fluoropolymer can be reduced and thus the durability of the tool (2) can be improved. In that case the extrusion product will slip evenly out from the tool (2), whereby the surface of the product is essentially smooth without transverse microscopic stripes repeated at a specific wave length.

Title: Treatment of cardiomyopathy by removal of autoantibodies
Inventor: SPAETHE REINER
IPC: C07K1/22
Filed: 1996-11-15
Abstract: Immunoapheresis treatment for cardiomyopathy comprises passing the patient's plasma over a column having coupled thereto a specific ligand for human immunoglobulin, thereby removing a significant portion of the immunoglobulin from the patient's plasma, and then reinfusing the plasma to the patient. The invention is the use of a specific ligand for human immunoglobulin in the manufacture of a column having the ligand coupled thereto, the column being useful for immunoapheresis treatment of a patient with cardiomyopathy. The specific ligand binds, and thereby removes, human autoantibodies which are harmful to cardiac tissue such as antibodies against .beta.1-adrenergic receptors, ADP-ATP carriers, .alpha. and .beta. myosin heavy chains, and adenine nucleotide translocators. Immunoapheresis treatment using the column results in improvement of hemodynamic parameters such as mean arterial pressure, mean pulmonary pressure, pulmonary capillary wedge pressure, right atrial pressure, cardiac output, cardiac index, stroke volume index, and systemic vascular resistance.

Inventor: TCHAKAROV BORISLAV J
IPC: E21B47/18
Filed: 1998-05-06
Abstract: A downhole tool containing instruments and a pulser is landed within a string of drill pipe. The pulser has a pulser body and an orifice on a lower end. A piston slides within a bore in the body and has a signal poppet on a lower end. In an extended position, the signal poppet extends into and obstructs the orifice to reduce the flow of drilling fluid. In an open position, the signal poppet does not obstruct the orifice to increase the flow of drilling fluid. A bi-directional solenoid valve is located above the piston and has upper and lower electromagnetic coils and an axially moveable rod. The rod is movable between a closed position in an opening in the body and an open position away from the opening. The rod is moved to both positions in response to the instruments which sends signals to the coils. The mud pulser also has an on/off flow switch which is actuated by the commencement of mud circulation. Initially, the rod is in the closed position. The instruments take various measurements which are communicated through the pulser to the surface in the form of mud pulses. A mud pulse is generated when a coil is energized to move the rod to the open position. This forces the piston and signal poppet into the extended position to restrict mud flow. The rod is moved to the closed position when the other coil is energized. The signal poppet creates pulses which are detected at the surface.
